Aim: On observing present Japanese society, we can find deep gaps between the present system and its probable future. One of the gaps may be due to the misconception that future societal make up is not definite. The aim of the current study was to investigate a future societal structure and to develop methods of adding a timed dimension policy to the societal structure. This is named "A theory of structuralism economics".<br> Methods: We developed 3 societal structure projection engines and applied a system of dynamics language to estimate the future total population of Japan.<br> Results: The Japan total population reached a maximum in 2005, and thereafter depopulation begun. The populations in the younger working age group (from 25 to 54 years old) and those in the elderly working age group (from 55 to 84 years old) became almost equal in 2010. As economic growth rate depends upon an increase in the working population, the increase in national income rate of Japan approached over 10% per year between 1950 to 1970. The increased working age population of the same period exceeded 2.5% annually. However, after 2005 depopulation began in Japan. In future, national income will decrease proportional to the working age population, but personal national income will hold almost unchanged.<br> Conclusion: We propose a new strategy for future society structure. The working age should be extended by 10 years. Labor power will come to exceed 60% of the population and will thereafter become stable.<br>
